1995 photo of Mars showing approximate size of the polar caps. The planet Mars has two permanent polar ice caps of water ice and some dry ice (frozen carbon dioxide, CO 2).Above kilometer-thick layers of water ice permafrost, slabs of dry ice are deposited during a pole's winter, [1] [2] lying in continuous darkness, causing 25–30% of the atmosphere being deposited annually at either of the ...
Images from the Curiosity rover show clouds nearly 80 kilometres high in Mars’s sky. Due to the low temperatures (below 150 K) at that altitude, the clouds were probably composed of CO 2 or dry ice , as opposed to water ice [ 3 ] [ 8 ] The interesting observation from the Curiosity rover is that carbon dioxide cloud formations were documented ...
Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738.. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from Earth with help from a telescope.

The rover used its Mastcam instrument to capture the area on the 4,352 Martian day of the pioneering mission. Images of the area from NASA’s Mars Reconnaissance Orbiter had shown light-colored ...
Estimates suggest that the initial partial pressure of N 2 may have been up to 30 hPa. [35] [36] Hydrodynamic escape in the early history of Mars may explain the isotopic fractionation of argon and xenon. On modern Mars, the atmosphere is not leaking these two noble gases to outer space owing to their heavier mass. However, the higher abundance ...
Mars will seem to disappear behind the full wolf moon Monday for many sky-gazers. Throughout January, also look up to see Venus, Saturn and Jupiter in the night sky.
Thus, for temperatures on Mars, "spring" is approximately the mirror image of "summer" and "autumn" is approximately the mirror image of "winter" (if the solstices and equinoxes are defined to be the beginnings of their respective seasons), and if Mars had a circular orbit the maximum and minimum temperatures would occur a couple of days after ...
